GeomeTREE (Two Intersecting Tetrahedra)

A polyhedron is a solid figure with many plane faces, typically more than six.A polygon has 3 sides or more and a polyhedron has 6 sides or more. A polyhedron has twice as many sides as a polygon. My ornament was a Stellated Octangula (Two Intersecting Tetrahedra.) It consists of two pyramids formed by connecting 8 triangles. I used blue and pink construction paper to form my ornament. I connected the vertices with tape and glue. All of the sides intersected by the way that they were formed. None of the planes on my ornament were parallel, but the segments formed two large pyramids.

Reflection- I worked by myself on this project It took me roughly about two class periods. I learned about Stellated Octangulas. In the word "Octangula," the word "octa" means 8. I used 8 triangles to form this ornament. The word "Tetrahedra," has the word "tetra," which means 4. Two intersecting- would stand for the two pyramids built into the ornament itself. The most challenging part was getting the triangles to stick together with the tape and the glue. I liked how the project was to make ornaments for the Christmas tree. The only thing fixable, was maybe an easier way to get the triangles to stick together to form the ornament.
